Complex Vector

A complex vector is a vector whose members are complex numbers.


Description

A complex vector is simply a vector of complex numbers.

Properties

The double conjugate of a vector is the original vector: a̿ = a.

Conjugation is distributive.

Distance

Note that a complex vector as z = [1+i 1-i] would, according to the conventional definition for distance, have a magnitude of 0. Only the zero vector should have a magnitude of 0 however.

Distance of complex vectors relies on conjugation. In linear algebra notation, the distance of complex vector z is equal to Tz.
